Neil,
You have done the right thing in asking if anyone has any experience of this wing.
It is easy to advise to buy new, but not everyone can afford to spend about £2500 on a wing.
It is possible to make significant savings by buying a used wing, but it can be a false economy if you have to replace it after a short time, but you may be lucky and find a wing that has had very little use. You should be completely sure it is the right type of wing for your level of experience, the right size, is certified, and then get it inspected by ‘The Loft’ or ‘Aerofix’. Preferably before you buy it.
